Optical communication connector

Abstract

Disclosed herein is an optical communication connector. A connector optically couples between a pair of plastic fibers and a pair of silica fibers, and a connector optically couples between the other ends of the silica fibers and a pair of plastic fibers. In such a construction, signal light is bidirectionally transmitted using these fibers. The connector is provided with one condenser lens within a casing. On the side of the transmission of signal light from the silica fiber to the plastic fiber, end surfaces of both cores P and Q are brought into intimate contact with each other. On the side of the transmission of signal light from the plastic fiber to the silica fiber, end surfaces of both cores P and Q are opposed to each other with the condenser lens interposed therebetween. The other connector is also constructed in a manner similar to the above connector.

What is claimed is:  
     
       1. An optical communication connector, comprising, within a common casing: 
       a first plastic fiber;  
       a first silica fiber;  
       a condenser lens for focusing light emitted and diffused from an end surface of a core of said first plastic fiber thereon so as to be launched into an end surface of a core of said first silica fiber;  
       a second silica fiber; and  
       a second plastic fiber,  
       wherein end surfaces of respective cores of said second silica fiber and said second plastic fiber are brought into intimate contact with each other so that signal light transmitted from said second silica fiber is directly launched into said second plastic fiber.
